Many people who use Amazon Fire sticks on their TVs might also have--or want to have--a subscription to HBO Max. Unfortunately, there is a contract dispute between Amazon and Warner Media (AT&T) about revenue sharing. So HBO Max is not yet available on the Fire stick menu.
But there is an elegant hack that will allow HBO Max subscribers to watch content on their TVs (smartphones and PCs are not a problem, since there is no Amazon inserted into the value chain).
Watch this video and follow the directions to install HBO Max on an Amazon Fire stick.
